My invention relates to playingballsand more particularly such'playingballs as compr se an inflatable rubber bladder contained within aleather or 'likecasing such as footare the balls of the prior artj'fAnother object of my invention is to-"secure more resiliency and weightinv a playing ball in a manner whereby the cost of manu I p embodimentillustratedfbeing disposed in I termediate' the ends of; the tube 8' and9 and facturing the ball will notbe exorbitant. 1

Another object'of my invention is to pros vi'de as an article ofmanufacture a resilient weighting girdle adapted' to" be placed Isequentfiguresgin' use the bladder lisiplaced. v i

around the inflatable bladder of, a playing ball 'such'as a football,and which when the bladder is inflated, will beinterposedbetween] thecontaining'c-asing and, the bladder and distended'by the inflationof'the bladder.

'Other objects of my invention and the invention itself will be betterunderstood by reference to the accompanying drawings referred to inthefollowing descrlptioncomw prised in this specification. I Referring tothe drawings Fig. 1 shows a plan view of a section of rubber tubingemployed in an embodiment of my invention as a weighting medium, and

' toadd to the resiliency of the ball;

Fig. 2 shows an end elevational view of the tubing placed overa footballinflatable bladder, and with the bladder not inflated tional view of acompleteifootball comprehended in my invention; and p Fig. 6 shows amedialtranSverSe section of the football of Fig. 5.

Referring to all of the figures in which.

like parts are designated by like reference characters, at 1 I show aninflatable bladder I made of sheets of thin rubber secured to Fig. '3shows a plan view of the bladder, slightly inflated and encompassed bythe-re- V gether in the usual-manner atiseams 2, there being twojof suchsheets placed face to face and secured together at the seams by a stripof like thinrubber material,3.--

Thetube 15"the cyl'indricalflform which may be obtained at the presenttime verycheaplyinthe form of sections of used rubber tire inner tubes,

may be' of differing forms, but preferably I make it ofsubstantiallycylindricalform, or as illustrated, a form closelyapproximating tosecure best results for the purposes herein 7 f rthand'accomplished by the ball of myinvention.1"- V,

I posed bladder and tubular girdle as shown In employing iny-V inventionin a playing ball suchasjalfootball, I place the super-;

in'th figures within the leather .casing of 5 ,thebalhand inflate thebladder by forcing air throughthetube 4 to expand the bladder. Theexpansion of the bladder-will; likewise expand the tubular girdle15 inlateral direc tions and willyreduce the length thereof a certain amountcommensurable with the degree of expansion] The tubular girdle 15 ispurposely made of a sufficient length so as to compensate for theshortening due to transverseexpansion when theball is inflated. I "findthat such a ballconstructed as described is not only heavier'thanit'would be. were "lie not the girdle '15 contained therein, but is; I

. stem 4 that the girdle when once positioned about the uninflatedbladdercontained-wlth- V in the casing illustrated. at 10, and thebladmore resilient than were the girdle absent and the bladder merelyinserted within the casing and inflated in the ordinary manner. I findthat due to the rounded form of the 1 inflated ball and the positioningof'theopenings 7 with reference to the inflatingtubular der inflatedthat'even where little or nocare isused in positioninggthe tubulargirdle with reference to the inflatable bladder and the i casinginterior, thatthe process of inflation spirit of my invention.

f havin a perforation inbrings about a positioning o-f-the tubularinterposed girdle'relative to the bladder and the casing so'that theweight on eitherside 'of the minor circumference of the ball will bebalanced. V e
